  • Emission reduction device and method for reducing the emissions of a transceiver device for a serial bus system
    Patent number: 11736314
    Abstract: An emission reduction device for a CAN bus system. The device includes an evaluation block for evaluating signals that are transferred differentially on two bus lines, the evaluation block being designed to form the sum voltage of the differentially transferred signals, and a comparison block for comparing the sum voltage in such a way that the difference between the sum voltage for a dominant bus state and the sum voltage for a recessive bus state has a predetermined minimum value, the recessive bus state being overwritable by a dominant bus state. For the comparison, the comparison block is designed to modify at least one property of the transceiver device via a setting in a block of the transceiver device until the difference between the sum voltage for a dominant bus state and the sum voltage for a recessive bus state has the predetermined minimum value.
